CAN BODY-ENDING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 697,784, dated April15, 1902. Application filed June 14,1901. Serial No. 641548. (No model.)

To 00% whom it may concern:

Be it known that I, HENRY C. BLACK, a citizen of the United States,residing at Oakland, county of Alameda, State of California, haveinvented certain new and useful Improvements in Can-Heading Machines;and I do hereby declare the following to be a full, clear, and exactdescription of the same.

The object of the invention is to provide a simple and inexpensivemachine for the placing of tops and bottoms onto can-bodies, theinvention residing more especially in the carriers which receive thecan-bodies and hold the same during the operation of ending or forcingthe tops and bottoms thereon and in the mechanism for driving thecarriers by a step rotation.

To comprehend the invention, reference should be had to the accompanyingsheet of drawings, wl1erein Figure l is a side view in elevation of themachine. Fig. 2 is an end view in elevation of the mechanismillustratedin Fig. 1 of the drawings. Fig. 3 is a detail top plan viewof the driv ecam, and Fig. at a broken detail part-sectional view of aportion of one of the can-body seats and of one of the fulcrumedPresser-plates for applying the ends onto the can-body.

In'the drawings the letter A is used to indicate the frame of themachine, and A the drive-shaft working therethrough. WVithinbearing-boxes A A attached to the frame, work the cross-shafts B B.These shafts are a distance apart, and upon each shaft a pair of disks BB are secured. In the peripheries of the disks are cut or formed thesemicircular seats or sockets a d, which seats or sockets during therotation of the disks register, so as to retain a can-body Otherebetween. The disks B I shall term the receivingdisks and disks Bthe retainingdisks. These disks may be of any suitable diameter, thenumber of seats or sockets cut therein depending upon the size of thesaid disks. I have shown the disks as being provided with twelve seatsor sockets; but the number may be increased or decreased, as desired.

To one end of the shafts B B the intermeshing gear-wheels C C areattached. By this form of connection the rotary motion of crossshaft Bis transmitted to cross-shaft B. To

the opposite end of cross-shaft B is secured the disk D, Within theperiphery of which the inclined slots a are cut. This disk constitutesthe drive-disk for the receiving and retaining disks, and the same hasimparted thereto a step rotation by means of the cam D Said cam issecured to the drive-shaft A and carries the rolls Z) b, Fig. 3 of thedrawings, which rolls during rotation of the cam alternately Work in andout of the slots a out in the periphery of the drive-disk D. To thedrive-shaft, inside of the frame A, are secured the wheels EE, whichwheels on their inner face are formed with the inclined cams 5 Theseinclined cams are arranged diametrically opposite and alternately engagewith the rolls d, attached to lugs d projecting from the presser-platesE E which presser-plates are fulcrumed at their lower end to thebed-plate E of the frame A. These presser-plates are normally heldoutwardly pressed by means of the pins d, which pins t within a socket(1 formed in the inner face of the presser-plates, and are held out wardby the pressure of spring 6. The pins (1 bear against the outer face ofthe receiving-disks B Figs. 2 and at of the drawings.

The can-bodies O are fed to the machine from the chute or runway F, theend of which terminates immediately above the receivingdisks. Thelowermost can-body rests upon the peripheries of said disks until thesame rotate, so as to permit of the can-body gradually seating itselfwithin one of the seats a, after which the can-body is carried away fromthe feed-chute toward the opposing or retaining disks. During thistravel of the receiving-disks the can-body is held within its seat bymeans of the curved guard-plate F. This guard-plate bears upon thecan-body until it has been carried into the seat a of theretaining-disks B The body will then be held within the registeringseats a a, it being embraced, so to speak, by the receiving andretaining disks. As thus held the canbody is advanced by a step rotationof the disks until point 5 is reached, when the top and bottom or ends Fare applied thereto. These ends are fed to the machine by the runways FF arranged at each side of the disks B B so as to be in line with theseats a a, of the receiving and retaining disks when they fullyregister. The bottom of the line of ends held within the respectivechutes rest upon the pins 01, projecting from the presserplates E Ebeing held in position between the said plates and the wall of thereceiving and retaining disks. By the time the canbody has been broughtinto horizontal alinement with the held can ends the wheels E E willstand in such positiou as to place the cams 6 into engagement with therolls d of presser-plates. As the cams b are carried past the rolls d bythe rotation of the wheels E E the said rolls cl ride upon theinwardlyinclined cams and gradually throw the upper end portion of thepresser-plates inward and force the ends F held thereby onto the canbody0, held within the seats a a. The moment the cams b are carried beyondthe rolls d the pressure of the springs e forces the presser platesoutward or away from the disks B B The presser-plates remain in theiroutward position until again forced inward by the inclined cams bbearing against the rolls d. After the ends have been applied to thecan-body the disks B B are moved by the step rotation so as to graduallyopen the closed seats and permit the ended canbody to fall from withinits seat in the receiving-disks into the discharge chute or runway G, bymeans of which they are conveyed to any suitable place of deposit.

The drive-shaftis driven by means of a belt working over a belt-wheel,(not shown,) or any other suitable form of drive mechanism may beemployed. This shaft, with the wheels and inclined cams thereon, is acontinuously-rotating one, although the motion imparted to the receivingand retaining disks is a step rotation. This rotation is procured, asstated, by the rolls b b, alternately working in and out of the slotteddrive-disk. By this step rotation the disks holding the canbody arebrought to a stateof rest sufficiently long to permit the ends to beapplied to the held can-body, as described.

I The receiving and retaining disks constitute oppositely-operatingmechanism for receiving the can-bodies and holding the same during theoperation of applying ends thereto.

By reason of the absence of header and re taining jaws movably securedto the oppositely-operating mechanisms I am enabled to dispense with thedelicate adjustment heretofore required in connection with machinery ofthis class.

Having thus described the invention, what is claimed as new, and desiredto be protected by Letters Patent, is-

1. In a can-body-ending machine, the combination with theoppositely-operatin g disks, of seats formed in the periphery of saiddisks,

the drive-shaft, means whereby a step rotation is imparted to theoppositely-operating disks, the fulcru med presser-plates for applyingthe ends to the can-bodies, devices carried by the drive-shaft wherebythe presserplates are operated to apply the ends, and means forsupplying the can-bodies and ends to the machine.

2. The combination in a can-body-ending machine,of theoppositely-operatingdisks,ofa series of can-body seats formed in theperiphery of each disk, of means for imparting a step rotation to thesaid disks, and devices whereby the ends are forced onto the canbodyduring the step rotation of the said disks.

3. The combination with the oppositelyoperating disks which receive andhold the can-bodies during'the operation of ending the same, of a seriesof can-body-holding seats formed in the periphery of each disk, aperipheral slotted drive-disk, devices for imparting a step rotation tothe oppositely-operating disks through the medium of the said drivedisk,and means whereby the ends are applied to the can-body during the steprotation of the disks.

4. The combination with the oppositelyoperating disks, of means forimpartinga step rotation thereto,the f ulcrumed presser-plates forforcing the ends onto the can-body held and carried by theoppositely-operating disks, and means by which the presser-plates areactuated during the step rotation of the said disks.

5. In a can-ending machine, the combination with the oppositely-operating disks which receive and hold the can-bodies, the driveshaft, devicesactuated by the drive-shaft for imparting a step rotation to theoppositelyoperating disks, the fulcrumed presser-plates by means ofwhich the ends are applied to the held can-body, and cam devices carriedby the drive-shaft for operating the presserplates. Y

6. The combination with the oppositelyoperating disks for receiving andholding the can-bodies during the operation of ending the same, of meanswhereby a step rotation is given to said disks, the spring-pressedfulcrumed presser-plates for applying the ends onto the can-bodies, andmeans for actuating the presser-plates during the step rotation of thereceiving and holding disks.

In witness whereof I have hereunto set my hand.
